This is perhaps the most common audio-video plug used on FPV receivers and goggles. It's the 3.5mm type with a TRRS (Tip, Ring, Ring, Shank) pinout. It can be used to create custom A/V cables for ImmersionRC, FatShark, and Flysight products.

This Velcro type strap material wraps around anything and sticks to itself for easy bundling. Great for cleaning up your ham shack cables, mounting R/C model battery packs, or an endless variety of other uses.
